Effect of Diet and Overnight Glucose Infusion on Fasting Respiratory Quotient Values. a RQ values obtained during the FSIGTT procedure, fasting versus post-glucose and insulin infusion. **Denotes significant difference within group between fasting RQ and RQ measured post-glucose and insulin administration between the same group, **P = 0.008 obese and lean. b Comparison of fasting RQ obtained prior to the FSIGTT procedure (baseline study visit), to RQ measured during the Pre-Intralipid phase of the test visit. #Denotes significant difference in LG group with respect to the LS group, P = 0.03. &Denotes significant difference in LG group with respect to the OS group, P = 0.04. ***Denotes significant difference within LG group for RQ measured after high carbohydrate diet + overnight saline or glucose with respect to fasting RQ measured during ad libitum dietary intake, P = 0.0009
